This is a workaround that is still in progress, see HSD 22020521218. If we don't have these NOPs we may see rendering corruption or even GPU hangs. While we still don't fully understand the issue from the hardware point of view, let's have this workaround so we can pass CTS and move things forward. If we need to change this later, we can. Besides, the impact is minimal. Shaderdb/fossilize report no changes for this patch. On our Blackops trace, the lack of this patch causes corruption in fog rendering (rectangles where fog was supposed to be shown don't show the fog). On dEQP-VK.graphicsfuzz.cov-array-copies-loops-with-limiters, without this patch we get a GPU hang.
